3. G. TRAGiiAi^s, IFebb and BerfJicIot (C. odora, Swartz; C. suaveolens, Swartz; C. maderensis, XoM;e).— 
A dwarf evergreen greenhouse Fern, from tlie South of Europe. Fronds glabrous, triangularly elongate, 
bipinnate, about six inches high, of a light green ; pinnae oblong-obtuse, sinuate-pinnatifid, the lower ones 
distant and pinnatifid. Eachis and stipes scattered over with narrow scales. Sori confluent. Fronds terminal, 
adherent to a somewhat tufted rhizome. 
4. C. MiCROPHYLLA, Swavtz. — An ornamental evergreen stove Fern, from the West Indies. Fronds slender, 
Somewhat lanceolate, broad at the base, bipinnate, one to one and a half foot long, pale green, slightly pubescent ; 
pinnules oblong, rather obtuse ; segments roundish-ovate, the sterile ones dentate. Eachis and stipes ebeneous, 
terminal, adherent to a short creeping rhizome. Sori continuotis, confluent ; indusium very small. 
5. C. ALABAMENSis, Kunze (Ptebis, Buckley; P. gracilis, Rugel). — An ornamental evergreen greenhouse 
Fern, from the Southern United States of America. Fronds glabrous, subcoriaceous, ten to twelve inches high, 
lanceolate, acuminate, bipinnate below; pinnae ovate -lanceolate acuminate ; pinnules of the lowest pinnae almost 
again pinnate the segments oblong-obtuse, of the upper ones entire, or auricled, or lobed at the base. Stipes and 
rachis deep glossy black, adherent to a creeping rhizome. Sori continuous on the lobes and pinnules. 
6. C. MiCROMERA, Link. — An evergreen greenhouse species, from Mexico. Fronds lanceolate -acuminate, 
bipinnate, about a foot long; pinnae linear-acuminate, pinnules rather obtuse ; segments obovate, deep green, the 
sterile erenate. Stipes, rachis, and midrib of pinnae ebeneous, and covered with narrow brown scales ; fertile 
segments concave. Sori continuous, confluent ; indusium very small. Fronds nearly all fertile, terminal, 
adherent to a short creeping rhizome. This is certainly distinct from C. mierophylla. 
7. C. PROFUSA, lumze (NothochLjENa pumila, of gardens). — A warm greenhouse Fern, native of Namaqua 
Land. Fronds slender, lanceolate, bi-tri-pinnate, six to ten inches long, light green ; pinnules oblong, rather 
obtuse, segments adnate, subdecurrent at the base, erenate at the margin. Sori confluent. Eachis, midrib of 
pinnai, and pinnules, scattered over with narrow elongated light brown scales. Fronds terminal, adherent to a 
slender creeping rhizome. 
8. C. HiRTA, Simrtz. — A very delicate evergreen greenhouse species, from the Cape of Good Hope. Fi-onds 
linear, lanceolate, subtripiunate, one foot long, pale green, and covered throughout with glandulose hairs ; pin- 
nules small, oblong-obtuse, pinnatifid ; segments erenate. Eachis and stipes brown, terminal, adherent to a 
rather erect rhizome. Sori distinct, subsequently confluent, on each segment of the fertile fronds. 
9. C. tenuifolia, Swartz. — A very tender deciduous greenhouse Fern, from the East Indies and New 
Holland. Fronds somewhat ovate or triangularly elongate, tripinnate, one foot long, light green; pinnules 
linear-acuminate ; segments oblong-ovate, deflexed. Eachis, stipes, and midrib of pinnie brown, and scattered 
over with narrow scales. Fronds terminal, adherent to a creeping rhizome. Soil round, subsequently confluent ; 
indusium very small. 
10. 0. EXiLis M. & H. — A delicate deciduous warm greenhouse Fern, the native country of which is unknown. 
Fronds very slender, glabrous, linear-oblong, one foot or more long, bi-tri-pinnate, lightish green ; pinnai ovate- 
triangular ; pinnules oblong, pinnatifid ; segments small, linear-oblong, adnate-decurrent at the base. Sori 
crowded on the teeth or segments. Eachis and stipes of a shining brown. Fronds terminal, adherent to a 
slender creeping rhizome. This Fern differs from C. tenuifolia, to which it is allied, in its slender and narrowly- 
elongated form ; and from C. Sieberi, which it resembles in outline, in its more delicate habit and texture : indeed 
we should have been inclined to refer it to the latter species, were it not that it never assumes any degree of 
stoutness and rigidity, but is slender, fragile, and membranous, and of very delicate constitution. 
11. C. Moiutziana, Kunze {G. 'elo'sqaia, Klotsch MS., not Willdenow). — A neat-looking evergreen warm 
greenhouse Fern, from Mexico and Venezuela. Fronds glabrous, triangularly elongate, tripinnate, nine inches 
to a foot long, lively green ; pinnules remote, deeply pinnatifid, with small roundish ovate segments, inferior 
ones entire, superior decurrent at the base, crenulate on the margin. Sori small, but few spore-cases on each 
segment. Stipes, rachis, and midrib of pinnae shining ; terminal, adherent to a creeping rhizome. This species 
has been introduced under the name of C. elongata by G. Norman, Esq.,' of Hull, from the Continental gardens. 
12. 0. marginata, Humboldt, Bonpland, ocaiL Kunth (C. rufescens. Link; C. CHRiiiopiiYLLA, Kunze; Allo- 
SORTIS ciliatus, Presl). — A very neat, evergreen, greenhouse Fern, from the Peruvian Andes and other parts of 
South America, and the West Indies. Fronds glabrous, somewhat ovate-triangular, from six to ten inches high, 
delicate green, tripinnate ; pinnules oblong, with oblong-ovate rather obtuse segments, decurrent at the base. 
Stipes and rachis black ; rhizome somewhat creeping. This plant is now very scarce in cultivation ; although, 
in 1840, it was growing freel3^ in the Birmingham Botanic Garden. 
13. C. CUNEATA, (Cassebeera, L. — A neat evergreen greenhouse Fern, from Mexico. Fronds 
glabrous, triangular, bipinnate, si.x to ten inches high, of a livelj^ green ; fertile pinnules oblong-acuminate, 
pinnatifid, with the segments narrowed at the base ; sterile segments oblong, wedge-shaped, and serrate at the 
margin. Sori linear continuous. Eachis and stipes ebeneous ; rhizome somewhat creeping. 
14. C. viscosa, Link. — A beautiful evergreen stove species, from Central America. Fronds triangular or 
pentagonal, one foot high ; branches tripinnate, light green, and covered throughout with viscid glandulose hairs ; 
pinnules oblong-obtuse, pinnatifid ; segments of the sterile frond dentate. Sori linear, continuous around eveiy 
segment of the fertile fronds. Eachis and stipes brown, terminal, adherent to a short creeping rhizome. 
lo. C. i.EN’DiGERA, Siiriiiz (C. LENTiGERA, inudciimr). — An elegant evergreen stove species, from Quito,
